Introduction - A concept conceived on the back of annoyance and frustration at UK mains plugs, then executed after months of theory and design implementation. Lo and behold the Seduction Audio Brilliant Finish Cryogenic Heavy Duty UK plug. 3 stage treatment process -  Stage one involves deep cryogenic processing. Pins and connectors are submerged in immersion liquid nitrogen and slowly cooled to -196 degrees Celsius (-320 Fahrenheit) for an extended period of time. Computer calibrated profile plateaus are used to slow the metals decent in temperature. A similar method is used then to ascend the metal to ambient room temperature. Finally all cryogenically exposed surface areas are then scrutinised and quality tested. Stage two includes brasso treatment on the plug inserts via slow buffer to slowly lift the top oxidised layer of metal and concludes with DeoxIT™ D5 contact enhancer. The result is a brilliant finish, primed ready to play audiophile plug. Stage three, the final stage is the addition of a silver contact fuse rated at 13amp. We finish all our plugs in a layer of ProGold™ G5 and all plastic-to-metal parts in CaliLube. The result - For audio applications an increased harmonic resolution, greater detail and more transparency in soundstage are common observations with plugs of this nature. A wider dynamic response throughout the audible spectrum, smoother highs and improved bass articulation culminates in a more organic presentation. For video applications, the benefits centre around significantly less noise in the video signal path. Expect a vivid, sharp and accurate colour rendition. The blacks deepen into an inky black and the scan resolution becomes quieter.
